These gears are provided with hubs a end a y ke b i e h d with said hub, and a pin 5 ooiineoted with said ygke for forming a handle by which it may be m e erwe l e d h we y n ieh er e ien he se m d a ar m d 1 .neite lih l y f th s a t and h Pi 6 passes outwardly throughthe left side frame member at? as show iin Fig. 4, and pivoted to said frame member at If is a lock arm h? having ptohes or hece s ses in the bottom sideithereo f adapted to receive the pin b and hold it iri'the desired position, and connected with the arm 6 is a spring? which is eei ed he fee d l e m mbe e at b, and the spri g 69 causes the lock arm 19 to bear firmly on the pin 6 and hold it in h d edpeei i in the op r o of he rhachiiih.

In the right sideof the bottom portion of the machine is mounted a shaft 0, which ranges at right ar gles to the shaft (1*, and

the shaft 0 is provided with two similar bevel ee e e? end the r t of w h operates in oo nect ion with the gear a on h ehe .end'th'e s eh of hi h peratesiri cg nection with the gear a on the e t h el e dehaft c i else pr vi ed with a drive wheel a of the sprocket, or y other s iteh t pe- The 'sid mme m m r e er eeh e ed by tie-rods 0 aiid 0 in the form of construction shhwn', and in the bottom portion of the frame is a downwardly and backwardly directed ch lte 0 Mounted in the top portio of the frameand, in the form of construotion shown, slightly forwardly of the shaft (2, and parallel therewith is a main cutter and drive shaft all provided at its right ,eiid witha belt wheel d by which it may -be driveh, or said shaft may be driven by a, crank or in any desired manner. The shaft 01 is also provided over the driye wheel 0 with a drive wheel ol of smaller ehi h ieh th n th Wheel e4 nd m unted on said wheels is a drive chain d. Mounted on the shaft (l is a cone shaped cutter e, composed of equally spaced disks 6 provided with cutting teeth 6 somewhat similar in form to saw teeth, and the cutter disks 6 increase in size from the left to the right side of the machine. The right upright member a of the frame is provided with a forwardly directed extension 03 which is inclined inwardly as shown in Fig. 3, and mounted in the front of the part (Z and the left side member a of the frame is a vertically movable slide f connected with the parts and a by a tongue and groove construction as shown at f in said figure. The slide f is provided at its bottom with a base member f and connected with the base of the frame is a yoke-shaped device f and connected with the base or bottom f of the slide f is a screw shaft f which passes downwardly through the top of the yoke-shaped device f, and said shaft is provided within said device with a beveled gear f which meshes with the gear a on the shaft a and the beveled gear f is threaded interiorly to correspond with the thread on the shaft f and the turning of the gear on the shaft f will feed said shaft, and the slide f up or down according to the direction in which the nut f is turned.

The slide f in addition to the base f is composed of vertically arranged side members f, vertical top guides f and a top cross head f together with side gages 9 connected with the side pieces f are adjustable laterally, said side gages being provided with transverse slots 9 through which are passed screws 9 and the gages 9 are-provided at their inner edges with forwardly directed members g and passing vertically through the cross head f at the top of the slide is a screw 9 on the lower end portion of which is mounted a jaw carrying head 9, the counter-part of which is the base f of the slide f which also constitutes a jaw carrying head, and by turning the screw g the jaw carrying head g may be raised and lowered as will be readily understood.

Mounted in the top of the frame is a transverse gage supporting plate h, which carries a gage 71?, said gage being provided with forwardly and backwardly arranged slots 7L3, through which are passed screws If by which the gage k is secured to the plate it, and said gage k is provided at its front edge with depending fingers h, as clearly shown in Figs. 2, 3 and 8.

The support plate It is provided at its rear edge with an upwardly directed lug it through which is passed a screw ]L7 which enters the rear edge of the gage If, and by means of which said gage may be adjusted forwardly and backwardly. In the preferred form of my construction, the jaw carrying head g on the screw 9' is provided with a detachable jaw i which is substantially triangular in form when viewed from the front, and said jaw is connected with the head 7' by a tongue and groove device as shown at i The jaw carrying head f or base of the slide f, is provided with a detachable jaw which is substantially triangular in form and which is detaehably connected with said jaw carrying head f by a tongue and groove construction as shown at 7' and when these jaws are in position as shown in Fig. 5, the bottom surface of the jaw 2' is inclined upwardly and to the right, while the top surface of the jaw is inclined downwardly and to the left.

In Fig. 5 of the drawing I have shown at a number of pieces of boards which are placed between the jaws i and j, and. the ends of which are to be provided with tongues and grooves to form inter-locking corner joints, and in practice it is necessary before placing the boards k in position to raise the slide f so that the bottom board, or that next to the jaw j, when said boards are inserted into position, will clear the teeth of the cutting disks o andv this position of said boards is regulated by the fingers 7a of the gage ]L2. The slide j is raised by throwing the pin 6 of the yoke Z) into the position shown in Fig. 1, in which position the gears a and on the shafts a" and 0 will mesh, and then turning the shaft cl or applying the power thereto. lVhen the slide f has been raised to the desired point the boards 7: are placed in position and the jaw 71 is moved down so as to press said boards tightly between said jaw and the jaw j. The yoke b and pin 6 are moved forwardly so as, to throw the gear a. on the shaft o in connection with the gear (1 on the shaft 0. This operation will reverse the direction of the gear on the vertical screw f and when the power shaft d is turned the slide f will be lowered and in this operation the cutter disks d are also rotated and the direction of this rotation is in the direction of the curve of teeth 6 on said disks. During this operation the slide f is gradually lowered and the boards 7.: are provided in the ends thereof with tongues Z1 and grooves 70 as shown in Fig. 5. It will be observed that these tongues and grooves are cut at an inclined angle to the longitudinal center line of said boards, and also at an inclination to the plane of the boards and the form of interlocking corner shown in F 9 is thus formed.

Instead of using the triangular jaws i and j shown in Fig. 5, other jaws m and m may be substituted therefor, as shown in Fig. 6, and the operation of the machine with these forms of jaws will be the same as when the jaws i and are employed, but the form of the tongues and grooves produced 'nected in the same plane, edges thereof made parallel, or two pleces' the ends of the beards when theiaws m an m e mpl ye w l e show in Fis- 6- and nterlocking er er imilar to that shown in Fig. thus be produced, but the tongues and grooves produced in this manner, as shown in Fig. 6, are'not of boards may be connected in the same plane without the opposite edges thereof being parallel; for if desired two pieces of boards may be connected as shown in Fig. 11 to form an ordinary miter joint. It

will be understood, of course, that the character of the connections or joints is determined by the manner in which the boards are inserted into the machine and the position in which the boards are held. The vertically arranged gages g on the slide f are adjustable laterally and said gages-may be adjusted so as to permit the boards 70 to be inserted at right angles to the shaft 03 instead of at an acute angle thereto, as when the slide f and gages g arein the position shown in Fig. 3. p

The gage/t in the top back portion of the machine, or the fingers if thereof limit the extent to which the boards'lc are inserted, and in this manner serve to limit the depth of the tongues and grooves formed in the ends of the boards, and it will be understoodthat at the beginning of the operation of cutting the tongues and grooves the slide f mustbe at such height that the boards 70 or the rear ends thereof will be over the front portions of the cutter disks 6 and as the slide f descends the ends of the boards 70 are thrown into contact with the teeth of said cutter disks.

In the operation of the machine as hereinbefore described, the dust or cuttings proranged shaft f so as to duced by the cutter disks 6 fall into the chute c" and are discharged at the back of the machine, and thus kept from falling into the gearing at the bottom ofthe mainframe.

It will be understood of course that the shaft (Z which constitutes the cutter shaft is in fact the main shaft of the machine, and the shafts 0 and a in the bottom portion of the machine are supplemental and auxiliary shafts, they and their connected gearing being operated by the shaft cZthrough the drive chain d to turn the vertically aroperate the vertically movable slide f.

My machine, as shown and described, is

' capable of forming inter-locking tongue and groove box corners, inter locking miter tongue and groove corners, and varlous other o e kieints, one at which is shown sacrificing its advantages.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is
